Error in R.java due to an XML file - android

So I created this new layout in another project and it somehow corrupted it (the project). R.java shows an error on a line
public static final class id
{
**public static final int 0dp=0x7f06003b;**
public static final int AutoCompleteTextView01=0x7f060031;
The line with the asterisks gives an error:
Syntax error on token "0d", delete this token
I thought it was just a fluke so I copied my layout xml to a working project and put it there. Bam. Same error generated in that project. I want to know if there is a problem with my layout XML.
The variable names are all generic because this was just a demo design. Can the problem be caused by the 0.5dp values I'm using?

Problem is with this
<EditText
android:id="#+id/0dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ems="10"
android:hint="A/C Number"
android:textSize="10sp" />
Do this
<EditText
android:id="#+id/EditText0dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ems="10"
android:hint="A/C Number"
android:textSize="10sp" />
Always follow naming conventions Never start any id with Numbers
After changing this You can Clean and Rebuild the project


id cannot start with a digit or a symbol except _

Scrollview doesnot appears after putting it in xml file in android

Inside my xml file i put a scroll view. But it doesn't shows in my program. I was confused because i checked for any color problems. Here is my xml file, can anyone specifies the reason it doesn't shown at there?
Please note: some characters from textview and edittext are removed due to character limitation by stack overflow.

I corrected some errors. This Might can help.

when keyboard is open layout should move above in android

I want to move my layout above when keyboard is on. I have tried with android:windowSoftInputMode="adjustPan|adjustResize". But this is not working.
When I click on EditText it should move above so that the TextView should be visible.

Add the line below to the activity this layout is inflated in. (AndroidManifest.xml) android:windowSoftInputMode="stateUnchanged|adjustPan"

EditText disapear if layout_width="wrap_content" and not layout_weight="1"

The next code is OK for Eclipse Layout Editor and Android Studio. I tested it in several mobiles and works fine but, in a Samsung GT-S6310N (Android 4.1.2), this EditText dissapears. It goes at the end of a LinearLayout that defines the Layout width. The Layout is showed in a Dialog using android:Theme.Dialog.
<EditText
android:id="#+id/et_clino"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ems="4"
android:inputType="numberDecimal"
android:text="89.9" />
I've solved this changing the code to:
<EditText
android:id="#+id/et_clino"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ems="4"
android:inputType="numberDecimal"
android:text="89.9" />
The question is: is wrong mi code or is a bug?

The reason for disappearing of the EditText is that you want to display items, which has total width greater than the width of the screen, so I've applied same layout_weight:"1" to all the elements inside the LinearLayout. May be this helps you for solving your issue.

view the two buttons side by side

I have two buttons Login and Scan. I want these buttons to be in a horizontal way just like in a single row. I tied making the layout horizontal. However it does not work. They should appear side by side. My code is as follows.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/imagesand"
android:orientation="vertical"
tools:context=".MainActivity" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="5dp"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/imagesand"
android:gravity="center"
android:orientation="vertical" >
<LinearLayout
android:layout_width="207dp"
android:layout_height="wrap_content"
android:layout_marginLeft="40dp"
android:layout_marginRight="40dp"
android:background="#drawable/loginbg"
android:gravity="center"
android:orientation="vertical"
android:layout_alignParentBottom="true"
android:paddingLeft="20dp"
android:paddingRight="20dp" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="User Name"
android:textAppearance="#android:style/TextAppearance.Medium" />
<EditText
android:id="#+id/emailid"
android:layout_width="156dp"
android:layout_height="45dp"
android:layout_marginTop="5dp"
android:background="#drawable/button"
android:hint="User Name"
android:inputType="text"
android:paddingLeft="10dp"
android:textAppearance="#android:style/TextAppearance.Medium" />
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:text="Password"
android:textAppearance="#android:style/TextAppearance.Medium" />
<EditText
android:id="#+id/password"
android:layout_width="156dp"
android:layout_height="45dp"
android:layout_marginTop="5dp"
android:background="#drawable/button"
android:hint="Password"
android:inputType="textPassword"
android:paddingLeft="10dp"
android:textAppearance="#android:style/TextAppearance.Medium" />
<Button
android:id="#+id/login"
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="Login"
android:textAppearance="#android:style/TextAppearance.Medium"
android:textColor="#000000"
android:typeface="serif" />
<Button android:id="#+id/scan"
and
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="scan"/>
</LinearLayout>
</LinearLayout>
</LinearLayout>

Just put both button in LinearLayout whose orientation must be horizontal

Simple use this..
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:id="#+id/textView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="left|center"
android:layout_weight="1"
android:text="Login"
android:textColor="#000000" />
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:layout_weight="1"
android:text="Scan"
android:textColor="#000000" />
</LinearLayout>
</LinearLayout>

Use this code:
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="5dp"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/imagesand"
android:gravity="center"
android:orientation="vertical" >
<LinearLayout
android:layout_width="207dp"
android:layout_height="wrap_content"
android:layout_marginLeft="40dp"
android:layout_marginRight="40dp"
android:background="#drawable/loginbg"
android:gravity="center"
android:orientation="vertical"
android:layout_alignParentBottom="true"
android:paddingLeft="20dp"
android:paddingRight="20dp" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="User Name"
android:textAppearance="#android:style/TextAppearance.Medium" />
<EditText
android:id="#+id/emailid"
android:layout_width="156dp"
android:layout_height="45dp"
android:layout_marginTop="5dp"
android:background="#drawable/button"
android:hint="User Name"
android:inputType="text"
android:paddingLeft="10dp"
android:textAppearance="#android:style/TextAppearance.Medium" />
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:text="Password"
android:textAppearance="#android:style/TextAppearance.Medium" />
<EditText
android:id="#+id/password"
android:layout_width="156dp"
android:layout_height="45dp"
android:layout_marginTop="5dp"
android:background="#drawable/button"
android:hint="Password"
android:inputType="textPassword"
android:paddingLeft="10dp"
android:textAppearance="#android:style/TextAppearance.Medium" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal"
<Button
android:id="#+id/login"
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="Login"
android:textAppearance="#android:style/TextAppearance.Medium"
android:textColor="#000000"
android:typeface="serif" />
<Button android:id="#+id/scan"
and
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="scan"/>
</LinearLayout>
</LinearLayout>
</LinearLayout>
</LinearLayout>

You can either wrap the buttons within a horizontal LinearLayout like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<Button
android:id="#+id/login"
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="Login"
android:textAppearance="#android:style/TextAppearance.Medium"
android:textColor="#000000"
android:typeface="serif" />
<Button android:id="#+id/scan"
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="scan"/>
</LinearLayout>
or use a RelativeLayout.

RealtiveLayout is the best choice:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button
android:id="#+id/button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/entry"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#+id/space"
/>
<TextView
android:id="#id/space"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"/>
<Button
android:id="#+id/button02"
android:layout_toRightOf="#id/button01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/entry"
android:layout_alignParentRight="true"
/>
</RelativeLayout>
Seems like you want two equal buttons, not wrapped content. I created a centered spacer using TextView, and relatively aligned to that. Left button to parent left and spacer, Right button to Left Button and parent right.

This should works:
Change these,
<Button
android:id="#+id/login"
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="Login"
android:textAppearance="#android:style/TextAppearance.Medium"
android:textColor="#000000"
android:typeface="serif" />
<Button android:id="#+id/scan"
and
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="scan"/>
with this,
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:orientation="horizontal" >
<Button
android:id="#+id/login"
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="Login"
android:textAppearance="#android:style/TextAppearance.Medium"
android:textColor="#000000"
android:typeface="serif" />
<Button
android:id="#+id/scan"
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="scan" />
</LinearLayout>

I don't know to correct this error. In xml layout i can see the button, but in the emulator its not visible or button not scrolled. also i want this two button in same line with left and right alignment.

You Specified inside scrollview second linearlayout as
<LinearLayout
android:layout_width="match_parent"
android:layout_height="454dp"
android:layout_gravity="bottom"
android:layout_marginLeft="20sp"
android:layout_marginRight="20sp"
android:orientation="vertical" >
change to
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_marginLeft="20sp"
android:layout_marginRight="20sp"
android:orientation="vertical" >
You Specified height fixed that why it does't display...
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_margin="3dp"
>
<Button
android:id="#+id/login_btn"
android:layout_width="wrap_content"
android:layout_height="50dp"
android:layout_weight="0.5"
android:text="Login"
/>
<Button
android:id="#+id/cancel_btn"
android:layout_width="wrap_content"
android:layout_height="50dp"
android:layout_weight="0.5"
android:text="Cancel"
/>
</LinearLayout>

Set your ScrollView's height to match_parent
<ScrollView
android:id="#+id/ScrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true" >
